DynoMax® - Ultra Flo™ Muffler

Instead of my stock one I installed this muffler and now it sounds much more aggressive. It is expensive a little, but quality is well worth it.

Looking to replace the exhaust system on my 1999 Dodge Dakota, RWD 3.9L Magnum V6, and wanted something a little more free flowing than stock. Did some research, and found this offering from Dynomax. Wanted stainless steel, and welded seams were a plus. Price was fair as well. Got the item fairly quickly. Inspected the muffler out of the box, no damage, but this ain't show piece. Welds are extremely sloppy, so either the robot on the line was off that day, or these are apprentice welds. End cuts for the inlet and outlets were pretty rough as well. I don't much care about appearance, so long as the thing is sealed. I gave it 2 stars for appearance in case you're looking for something nice. For a universal fitment muffler, this was a no fuss install for my truck. Good bang for your buck, if appearance isn't important. Sounds good at idle, a little raspy on acceleration, and an obvious drone at 2500-3000 RPM on acceleration. I can deal with it. Overall, I'm satisfied.

The '14 V6 Tacoma comes with an offset to offset muffler. The Dynomax Turbo is not available in that design. I bought the offset to center model. Since it is reversible, I figured the muffler shop would be able to install it. They did have to add one section of pipe to make everything fit and install new hangers. The muffler cost about $70 and the install was $125. I was hoping he'd charge only $100. Nevertheless, that was still a lot lower than the $250 estimate had I bought the Magnaflow muffler from the muffler installer. The Dynomax Turbo is just a little louder than factory; the exhaust sound at road-speed is pleasant. It is not the "ratty" sound you hear from single or dual exhaust V6's. I will add that my old '94 V6 4.0 liter Ford Ranger sounds a heck of a lot better with just the factory exhaust. I suppose that has something to do with OHV engines compared to OHC. OHV delivers more "lope" sound. However, after 22 years in the Ranger, it was time for something new. Besides, the 156 hp of the ranger does not compare to the 236 hp of the Tacoma. Same size engine, but 22 years of tech change equals more right-foot excitement.

Great muffler. I had to do some welding and modification to the tail pipe in order to fit (expanding the ends and cutting of the tail pipe), but once attached it seems to work great.

I like it easy to install and gives my Jeep Liberty a nice deep tone and little bit more power.

Well made, has a good sound tone quality, pipe connections were oversized but was able to adapt. otherwise a perfect fit.

The product arrived just in time, I installed it on my car and it gained a surprising amount of horsepower. Great product, reasonable price, and fast shipping. Thanks!
